Short and Long Term Goals
Act as a Resource for agencies
Review specifications
Identify sources and validate
national data – Survey DOTs
Promote free webinars on CPR
Improve participation with TCCC
for training and promotion
Short and Long Term Goals Educate stakeholders on Concrete Pavement
Management
Document and communicate the benefits of CPR
Support the development of training in the area of
concrete pavement preservation
Promote participation in the Pooled Fund study
on Accelerated Joint Deterioration
Evaluation of Seal/No Seal concrete joint
performance
Increase industry presence and participation in
AASHTO TSP2 Regional Partnerships
Promote sustainability benefits of maintaining
rigid pavements
New Goals
Partial Depth Repair Guide -
National Concrete Pavement Tech
Center
Our team members are actively
supporting effort
Development of a true PCCP PP
curve to promote true LCCA costs
of pavements
Pavement Preservation Workshop
National Concrete Pavement Tech Center
1-2 day workshop on Concrete Pavement
Preservation
FHWA funded
Seal/No Seal Concrete Joint Performance
What is the best practice?
Sealing at new construction?
Sealing as Maintenance?
On-going Research Tasks with
various states
Pooled Fund study on Accelerated Joint Deterioration
Made up of Mid-Western States
Have to answer the “Why”
questions of this new phenomena
Accelerated Joint Deterioration
Survey Status on the PCCP Preservation Trigger Values
Survey sent via email to all 50
state DOTs in May 2010
Quality of responses are very good
Update to be provided this
afternoon
And we are a Resource

Why?
Closing the loop on Asset
Management
Design
Use/Preservation
End of life
Collect more data? No
Collect the right data
Traditional Concrete Pavement Preservation
?
Purpose of Survey Establish Estimate of Percent of
Concrete Pavement in Each
Network
Establish State-of-the-Practice in
States’ Management of Concrete
Pavements
Review Distress Data Collection
Procedures of Agencies
Identify Opportunities to Improve
Practice
Connection of Design to PMS
(Closed Loop)
Survey Approach
FHWA Provided Data Base of State
PMS Contacts
Email Survey to the State Contacts
Follow Up Emails for non-responding
states
Lose a Couple Surveys Here and There
Prepare Draft Report
Transmit Report to States & Full ETG
for Comment
Finalize Report
States Responding w/ Trigger Values

So What Did We Learn
Lots of Ways of Doing PMS
(Triggers)
About 60% of States Appear to
be Managing Concrete
Preservation with Triggers
No Consistent Methodology
Most States Use Composite
Statistics
Is Joint Sealant Cost Effective? FHWA Sealant Effectiveness Study
AASHTO New Design Guide
Potential Follow Up Activities
Develop Best Practices
Reports from Selected States
Research What Parameters
Should be Used to Manage
Concrete Pavement
Preservation
Establish Life Extension of
Each Concrete Preservation
Treatment
Engage TSP2 Partnerships in
Identifying Opportunities and
Solutions
FHWA Facilitate State
Showcases at TSP2
Compare Survey Results to
FHWA Pavement
Preservation State Appraisals
and FHWA PMS Research
Review
Compare State/Federal PMS
Curves to LTPP Concrete
Performance Curves
Develop Procedures for
Accounting for Strategy Cost
Increases Over Time
Provide Update to FHWA
